IMPROVEMENT IN THILL-COUPLINGS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, THOMAS G. WALTER, of the city andcounty of- San Francisco, State of California, have invented an Improved Pole and Shaft Attachment to Vehicles; and I do hereby declare the following description and accompanying drawings are suiiicient to enable any person skilled in the art or science to which it most nearly appertains, to make and use my said invention or ii'nprovemeuts, without further invention or experiment.

The mun-emessence of my invention consists in a peculiararrangement of the several parts of a device,

to be fully described below, for securing the thil'ls or or shafts-item those ordinarily employed, is in the arrangement of that part which attaches to the vehicle. At the rear end of the pole or shafts I secure a metal or other bar, which is represented by A, and is similar to that commonly employed. The extreme end of this bar' is reduced in size, forming a shoulder at (l, and is turned so as to form a semicircle, (i. Another semicircular piece of metal or segment, I), is jointed or hinged to the end of 0, so that Whenit is closed-a perfect band or ring is formed.

To. the segment I) is secured an extended projec-' 'tion, E, which, when the segment is closed, its into thereduced portion of the metal bar A, forming-a close joint against the, shoulder a.

A spriug,'b, witlrenlarged head, .is attached to the end of the projection E, and extends a short distance along the bar A, the bar being slotted to receiv'e'it, so that, with the exception of the enlarged head, it will ile flush with the top of the bar.

.axle, being that portion next to the journal.

stantially as described.

A square band, F, which encircles the bar A, is then slipped over the projection E, until it has passed the enlarged head, thus binding the two together, the head preventing it from moving from its position.

B represents simply a short section of the front iron At the proper or suitable point on this iron axle I cut away or turn down a width of metal, as at G, sufiicient to receive thewi'dth of the bar A on the pole or shaft, until it is of the proper size to be received in the ring or band formed onthe end of the pole or shaft.

if desired, the part at G can be turned sufiiciently wide to allow of rubber bands .to be placed on each side of the bar A, in order to prevent rattling.

To attach the pole or shafts to the axle, the segment Dis opened on its hinge, and the turned portion of the axle received in the ring, after which the segmcnt D is closed and secured by the band, which prevents the two from separating. By this means the pole or shafts can be attached to -vehicles so as to be perfectly safe and reliable. There will be no danger of any of the parts breaking, as the strainwilhcome upon the bar at O. a

The usual bolts and nuts are also dispensed with,

- thus avoiding the liability of frightening the horse by the nut coming off, and the pole or shaft becoming detached by the withdrawing of the bolt.

Having thus described my invention,

What I claim, and desire to secure by Letters Patent, is'

The arrangement of the several parts of the abovedescribed device, when the movable part of the eye I) is hinged directly to the other part, 0, while the prolongation l of the former is secured in the recess at a by the band or slide F,'he1d by the spring 1), sub- In witness whereof, I have-hereunto set my hand anti seal.
